The table shows the battery life of four different mobile phones:
Mobile Phone Battery Life Phone
Battery Life (hours)
A 20
B 25
C 10
D 18
If 8.45% of the battery life of each mobile phone is used in a day by a typical user, which mobile phone would use a total of 1.69 hours of battery life in a day?
Phone A
Phone B
Phone C
Phone D

Answers

Answer 1

Answer:

Using quick mental math, we can do 8% of 10 to get 0.8, which is close to the value of 0.0845*10. Also fairly quick is moving the decimal point over 1 spot to the right and we go from 0.0845 to 0.845 and that rounds to 0.8 when rounding to one decimal place. Recall that 8.45% = (8.45/100) = 0.0845

If you want to compute out the four results with a calculator, then it would look like this:

0.0845*20 = 1.69

0.0845*25 = 2.1125

0.0845*10 = 0.845

0.0845*18 = 1.521

and this shows that no other result (but choice C) is close to 0.8

So that's why the answer is choice C

What is the mean absolute deviation of Sherwin's homework scores? HELP

Answers

Answer:   6

======================================================

Explanation:

First we need to find the mean.

Add up the values to get 20+13+3 = 33+3 = 36

Then divide that sum by 3 because we're dealing with three values

We get 36/3 = 12.

The mean is 12.

--------------------------

From here we subtract the mean (12) from each data value of the set {20,13,3}

So we get these differences

20-12 = 813-12 = 13-12 = -9

Here's where the term "absolute" comes in. More specifically, we'll use absolute value. This is to ensure we don't get a negative value when we subtract. So whatever results above are negative, we just flip to the positive version when we apply absolute value.

|20-12| = 8|13-12| = 1|3-12| = 9 .... this value is now positive

--------------------------

The set of results we got were {8, 1, 9}

Let's compute the mean of this new set

Add up the values: 8+1+9 = 9+9 = 18

Divide by three:  18/3 = 6

The mean absolute deviation is 6.

Answer:

6

Step-by-step explanation:

The mean is the values divided by how many values there are.

20 + 13 + 3 = 36              36 / 3 = 12

The mean deviation is the absolute value of the difference between the mean and the values.

|20 - 12| = 8

|13 - 12| = 1

|3 - 12| = 9

The mean absolute deviation is the mean of those values.

8 + 1 + 9 = 18

18 / 3 = 6

Answer:

Number of Starbursts= 66

Step-by-step explanation:

Method:

The first step in working out the number of Starbursts in the bowl is to add the the ratios of 3 and 4, this gives you 7.

The next step is to divide the total number of sweets which is 154 by the value of 7, this gives you 22. This is because we are trying to find out the value of one in the ratio.

The final step would be to work out the number of Starbursts in the bowl. This can be done by multiplying 22 by the ratio for Starbursts which is 3, this gives you 66. This means that out of 154 sweets 66 of them were starbursts.

Set by step:

1) Add 3 and 4.

[tex]3+4=7[/tex]

2) Divide 154 by 7.

[tex]154/7=22[/tex]

3) Multiply 22 by 3.

[tex]22*3=66[/tex]

KAHULUI, Hawaii — It had been 17 days since anyone had seen Amanda Eller. Her car was spotted near a trailhead in a vast forest reserve in Hawaii, and thousands of search volunteers were scouring the jungles and streams nearby.

On Friday afternoon, less than an hour after her family announced a $50,000 reward for information, rescuers found Ms. Eller with a broken leg, sunburns and scrapes, and a torn meniscus in her knee.

She was malnourished and dirty. But alive.

“I wanted to give up,” Ms. Eller, 35, said from her hospital bed late Friday night. “But the only option I had was life or death.”

Ms. Eller, a physical therapist and yoga instructor, said she lost her way in the Makawao Forest Reserve on the northern side of Maui on May 8, turning a three-mile hike into a two-week fight for her life.
